The title tells all, they may come from ANY anime or manga, so long they are wearing a school uniform. Please, you can submit more then one! But don't go crazy and go and submit 10 or so, because quality is less likely to be good.

Eh, use Paint, Photoshop, but TRY your best!

It has a long deadline, so relax, relax! (2 months)

Even if you didn't win, it doesn't matter at all. It just means that you have more to work on, and prefect. Keep trying! :D
